To all whom it may concern:

Be it known that I, MARK P. GILLEN', citizen of the United States, and.a resident of San Diego, in the county specification.

'My lnvention relates. tov vehicles, ,cspe

cially to automobiles, and the main object thereof is to provideresilient means be tween the frame and axles to take stra ns in I ayielding though gradually resisting manner, whereby shocks to theoccupants of the vehicle will be avoided while riding over rough roadsor any surface inequalities.

A further object is to accomplish the above result by means of armsarranged in the manner of toggle-levers but with extended members whichserve as the carrying means for certain fully described.

My invention is fully set forth in the fob lowing specification, ofwhich the accompanying drawings form a part, in which llkecharacters'refer to like parts in each of the springs to be hereinafterviews, and in which Figure 1 is a side elevation of one of my devices inoperative connection with the frame and an axle housing of a vehicle,and in normal position; Fig. 2 is a similar view but with the parts indepressed positions, as when taking a jolt; Fig. 3 is a section taken onthe line 3-3 of Fig. 1; and Fig. 4 is a view similar toFig. 2 butshowing a modification thereover.

Referring to the drawings, 5 represents a portion of the frame of avehicle, 6 one axle thereof, and 7 the housing for said axle, as at therear wheels of automobiles, and I end of reach axle and ,dispense withthe conprovide one of my ifsilient devices at each ventional springs noI used, a description of one of'these devices being deemed sufiieientboth for illustration and description.

Each device. consists of two arms 8 and 9 pivoted to the fra 5 and toeach other at 10 and downwardl? diverging, these arms being similar toeach other and provided, each, with headed pins or screws 11 and 12adjacent the lower ends thereof, and with.

headed pivots 13 interposed between the pixie 12 and the pivotl'lflt;The ivots 13 con nect the respective arms 8 an 9 with equalizing levers14 and 15 in "turnpivoted to- Specification of Letters Patent.

gether and to a saddle 16 at 1?, the latter bea mg secured to the axlehousing 7 by means @of a strap 18 or a suitable equivalent;

The pins 11 of the arms 8 and 9 serve'as anchors for coil springs 19,and the pins 12' for springs 20 and 21 in turn held upon the pivot 17,while the pivots'13, serve as anchors for springs22, the arrangement ofsprings one of the arms 8 and 9, in

in. the scope of the appended claims and .within the spirit of theinvention.

one side of the arms 8 and '9 shown as on v being duplicated on theopposite side thereof, thereby permitting the use of less powerfulsprings than if only one set was an ployed at one side of said arms.

he levers 14 and 15 areprovided, each with a T-head or end which servesas a bearing for the movement of the respective the movement of saidarms and levers with respect to each other and as shown in Figs. 1 and2, and the upper ends of the arms 8 and 9 are so formed as to presentbearing surfaces for each other in any of the possible positionsthereof.

The modification shown in Fig. 4 is substantially the same as the formalready described, with the simple exception that the springs 19 aresupplanted by springs 23 and 24: connected to the axle housing or to thestrap 18, this form removing any springs from beneath the axle butoperative in the manner 'of the first form. I

As will be noted by reference to the normal and abnormal positions shownin the drawings, the lowermost springs are affected in the greatestdegree, the springs 20 and 21 in somewhat less degree, and the springs22 in least degree, this being because of the difi'erent lengths ofmovement of the respective pins and pivots on the arms 8 and 9, but allof the springs contribute to the strains brought to bear thereon inyieldingly resisting the same, the resistance being gradually increaseduntil the strain is overcome after which'the parts resume normalpositions.

It will also be noted that the positive bearings between the saddle,equalizing levers, and arms, tend to prevent lateral movement of theframe 5 with respect to the vehicle Patented Nov. "2, .1216. Applicationfiled June 21, 1916. fierial No. 164,952. i i

wheels, and areresisted by the springs in a resilient manner and, whileI have shown two perferred embodiments of my invention, it will beobvious that changes may be made thereover provided suchchanges-comewith- Having fully described my invention, what I claim asnew, and desire to secure by Letters Patent, is:

1. In a wheeled Vehicle, a suspension for the frame comprising, at eachaxle end, two arms in pivotal connection, two equalizing levers pivotedto the respectivearnis and to each other, a plurality of springs joiningsaid arms, and a plurality of springs joining said arms with the pivotof said levers.

In a wheeled vehicle, a suspension for the frame comprising, at eachaxle end, two downwardly divergent arms pivoted together and to saidframe, two upwardly diverging levers pivoted together and to therespective arms, a saddle on the axle in pivta connection with saidlevers at their common pivot, a coil spring joining the upper portionsof said arms, at each side thereof,

springs at the lower ends of said arms re sist'ing separation thereof.

3. In a wheeled vehicle, a suspension for the frame. comprising, at eachaxle end, two

downwardh divergent arms pivoted t07.

gether and to said 1 ame, a saddle on said axle, two upwardly divergentlevers pivoted together and to said saddle and to the respective arms, acoil spring at each side of said arms oining the latter at their pivotalconnections with said levers, two coil springs at each side of said armsjoining the latter with said saddle, and two springs at each side ofsaid arms joining the outer ends thereof with said axle.
